iFi Audio Pro iDSD Signature DAC / Headphone Amplifier
The iFi Audio Pro iDSD Signature builds upon the strengths of its award-winning predecessor, delivering high-quality music in a way that will leave you breathless. Whether you're using it as a standalone unit, a DAC/preamp, a network streamer, or a headphone amplifier, the Pro iDSD Signature will exceed all expectations.
The Pro iDSD Signature boasts a sonically darker background and a punchier bass. Its power-supply components have been upgraded, resulting in a 300% decrease in overall system noise. And let's not forget the precisely matched NOS GE5670s tubes, the added support for USB1.0 (PS4/PS5), and the new aluminium remote control.
The Pro iDSD Signature also features a quad-stack DAC - 4 x DACs in an interleaved configuration - for exceptional resolution. Its powerful XMOS XU216 X-Core 200 series chipset allows for state-of-the-art audio support, including MP3, 32-bit/768kHz PCM, DSD512, 2xDXD, and full MQA decoding.
Thanks to the Crysopeia FPGA Digital Engine, the Pro iDSD Signature brings studio-grade DSD remastering to a wider audience. It can even upconvert PCM and DSD files to DSD512 and DSD1024. And with the convenience of controlling it all from an app in the palm of your hand, there's truly nothing else like it.
E-tailoring is another unique feature of the Pro iDSD Signature. You can listen to your music in solid-state, tube, or tube+ modes - all at the flick of a switch. And with the Crysopeia FPGA Digital Engine, you have several options for digital filtering, including the GTO filter, Bit Perfect, Bit Perfect+, Apodising, and Transient Aligned filters.
The Pro iDSD Signature also offers a discrete, fully balanced Class A amplifier stage with adjustable gain. And when it comes to streaming options, the possibilities are endless. You can stream wirelessly from Tidal, Spotify, Napster, QQ Music, and more. Or, for a wired connection, use Airplay, Ethernet, DLNA, or connect to a hard disc drive, USB memory stick, or SDHC card.
The Pro iDSD Signature comes with the flagship iPower Elite, coupled with a re-crafted power supply board that reduces noise by up to 300x. We've left no stone unturned in our quest for the cleanest, purest power - both within and without.

Stacked. With tech.
The Pro iDSD Signature uses a quad-stack DAC – 4 x DACs in an interleaved configuration – to deliver exceptional resolution.
The powerful XMOS XU216 X-Core 200 series chipset processes incoming digital data and enables the Pro iDSD Signature to provide state of the art audio support – from MP3, 32-bit/768kHz PCM, DSD512, 2xDXD and full MQA decoding.
Thanks to the Crysopeia FPGA Digital Engine the Pro iDSD Signature brings studio grade DSD remastering to a wider audience. It can upconvert PCM and DSD files to DSD512 and DSD1024.
And all controlled from an app in the palm of your hand.
E-tailoring
The Pro iDSD Signature, like its predecessor, takes sonic tailoring to the extreme.
Listen to the your music to in solid-state, tube or tube+ modes, your choice, all at the flick of a switch.
Our Crysopeia FPGA Digital Engine strikes again as it enables the Pro iDSD Signature to offer several options when it comes to digital filtering. The GTO Filter adds gravitas and a new dimension, and while the Bit Perfect, Bit Perfect+, Apodising and Transient Aligned filters give you even more choices to tweak the sound.
The discrete, fully balanced Class A amplifier stage offers adjustable gain.
Your choice. The only choice.
- Stream wirelessly from Tidal, Spotify, Napster, QQ Music and more
- Use Airplay to enjoy playback from your iPhone, iPad or Mac
- Go wired via an Ethernet connection to play from a router or NAS (Network Attached Storage)
- Use DLNA network audio playback with smartphones, tablets, Windows/Linux computers
- Connect to a hard disc drive (HDD)
- Pop in a USB memory stick or SDHC card
And with a variety of headphone outputs – Single-Ended 6.3mm, S-Balanced 3.5mm and Balanced 4.4mm – the only choice is your choice.
Power cleans. Absolute.
The Pro iDSD Signature ships with our flagship iPower Elite.
Coupled with the re-crafted power supply board which offers up to 300x lower noise, the music is buttery smooth.
Within and without – we left no stone unturned in our quest for the cleanest, purest, power for the Pro iDSD Signature (same for Pro iCAN Signature too!)

Data is sent to the Memory Buffer from all inputs. Here it is de-jittered to eliminate any transmission of source jitter to the DAC output. The data from the Memory Buffer is further re-clocked by the low-jitter Global Master Timing® clock, which also drives the X-Core 200 and FPGA. |
|
|
The Pro iDSD Signature employs the new XMOS XU216 X-Core 200 Series 16-Core processor. All-digital processing is Bit-Perfect unless particular digital filters are explicitly selected. |
|
|
MQA (Master Quality Authenticated) MQA is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download. The Pro iDSD Signature adopts MQA technology to receive and decode MQA audio and provide master-level sound. |
 |
The amplifier audio circuit is fully discrete, fully-balanced with either tube or J-FET input switchable, bipolar second stage and MOSFET-buffered bipolar Class A Power stage. |
|
|
Galvanic isolation is the ‘holy grail’ of computer audio. All inputs are galvanically-isolated (including USB). The USB input section has its own separate power management system with multiple regulators and filtering operating from the galvanically-isolated voltage generated to power this section.
|
|
|
The Pro iDSD Signature has a ‘quad stack’ of Bit-Perfect DSD and DXD DACs by Burr-Brown. The ‘interleaved’ configuration means up to 8 pairs of differential signals can be used and mixed, equal to 4 pairs of signals per channel. |
|
|
Upsampling to DSD1024 has previously only been available to a select few. The Pro iDSD Signature makes it available to a wider audience. The DSD1024 remastering is handled by the Crysopeia® FPGA and this is where we believe the FPGA excels. |
|
|
With LINKPLAY™ WiFi/network playback, built-in Spotify and Tidal, and wide protocol support for 32-Bit/192kHz and DSD64, the Pro iDSD Signature can be also used without a computer to stream audio directly. |
|
|
Unlike other amplifiers that have the same circuit and just switch in/out the tube section, the original Pro iDSD and now the Pro iDSD Signature are among the very first to have two individual input circuits – one tube (General Electric 5670 tubes!) and one solid-state. This results in the ‘best sonics of both worlds’. |
|
|
The amplifier audio circuit is fully discrete, fully-balanced with either tube or J-FET input switchable, bipolar second stage and MOSFET-buffered bipolar Class A Power stage. We’ve given the Pro iDSD Signature an extra Tube+ setting. This reduces overall loop-gain and negative feedback to the minimum and presents a different sonic perspective between the tube’s natural harmonics and transient performance. |
|
|
The Pro iDSD Signature is packed full of premium components – a Japan Alps rotary volume potentiometer, audio-grade ELNA Silmic capacitors and a bank of Elna Dynacaps ‘super capacitors’.
